Frequently asked questions
Common questions about ONDRIVES.US from 3G Electric.
What are the key specifications of ONDRIVES.US precision ground rotary shafts?
ONDRIVES.US precision ground rotary shafts are available in inch and metric sizes. Inch series shafts are made from 303 stainless steel with a diameter tolerance of -0.0002 in and hardness of 83 HRB. Metric series shafts are made from 316 stainless steel with a diameter tolerance of -0.005 mm and hardness of 79 HRB. Standard lengths include 36 inches for inch series and up to 800 mm for metric series. End finishes are either chamfered or edge break, depending on the part number. These shafts are designed for use in motors, pumps, and other rotating equipment where precise fit and corrosion resistance are required.
What materials are used in ONDRIVES.US threaded stud mounts?
ONDRIVES.US threaded stud mounts are constructed from steel with a zinc-plated finish. This provides corrosion protection and a durable mounting interface. The mounts are available with journal diameters ranging from 6 mm to 10 mm and corresponding stud threads such as M5-0.8, M6-1, and unified inch threads. The zinc plating helps resist oxidation in typical industrial environments, making these mounts suitable for securing motors, pumps, pulleys, and gears to machinery. For specific chemical or washdown environments, additional protection may be required, but the standard zinc plating offers a balance of cost and corrosion resistance for general power transmission applications.
How do I select the correct ONDRIVES.US rotary shaft for my application?
Selection depends on diameter, length, material, and tolerance requirements. First, determine the required shaft diameter and length based on your mechanical interface. Then choose the material: 303 stainless steel for inch series with 83 HRB hardness, or 316 stainless steel for metric series with 79 HRB hardness and better corrosion resistance. Tolerance is fixed per series: -0.0002 in for inch and -0.005 mm for metric. End finish options include chamfered or edge break. Consider the operating environment; for corrosive conditions, 316 stainless steel is preferred. 3G Electric can assist with cross-referencing part numbers and confirming availability for specific SKUs.
What are the available sizes for ONDRIVES.US threaded stud mounts?
ONDRIVES.US threaded stud mounts come in several sizes to accommodate different mounting needs. Metric options include journal diameters of 6 mm, 8 mm, and 10 mm, with corresponding stud threads M5-0.8, M6-1, and larger. Inch options include a 0.375 in journal diameter with a 0.438 in journal length. All mounts are steel with zinc plating. The journal diameter refers to the portion that fits into the mounting hole, while the stud thread provides the attachment point for the component. These mounts are typically used to secure motors, pumps, and other rotating equipment to a base or frame, ensuring alignment and stability.
Can ONDRIVES.US shafts be used in high-temperature applications?
ONDRIVES.US precision ground rotary shafts are made from 303 and 316 stainless steels, which have moderate high-temperature resistance. 303 stainless steel is generally suitable for temperatures up to about 400°C (752°F) in intermittent service, while 316 stainless steel offers better creep resistance at elevated temperatures. However, continuous operation at high temperatures may affect hardness and corrosion resistance. For specific high-temperature applications, consult the material properties and consider factors such as thermal expansion and load. 3G Electric can provide material certificates and technical data upon request to help verify suitability for your operating conditions.
What is the difference between 303 and 316 stainless steel in ONDRIVES.US rotary shafts?
303 stainless steel is a free-machining austenitic grade with good mechanical properties and corrosion resistance, but it is not recommended for severe corrosive environments. It offers a hardness of 83 HRB in ONDRIVES.US inch series shafts. 316 stainless steel contains molybdenum, which improves resistance to chlorides and acids, making it suitable for marine and chemical applications. ONDRIVES.US metric series shafts use 316 stainless steel with a hardness of 79 HRB. The choice depends on the environment: 303 for general industrial use, 316 for corrosive conditions. Both are non-magnetic in the annealed condition and can be machined or welded, though 303 is not typically welded due to sulfur content.
